FIELD DEFINITION AND SCOPE

Geographic area codes (GAC) for geographic areas associated with the community information entity. Codes from: MARC Code List for Geographic Areas. The source of a local code in subfield $b is indicated in subfield $2. The source of codes in subfield $c is ISO 3166, Codes for the representation of names of countries and their subdivisions - Part 1: Country codes or Part 2: Country subdivision codes. Information in textual form about the geographic area served may be contained in field 522 (Geographic Area Note).

Examples of GAC use would be for the geographic area the program serves or the geographic area where an organization is located. A more precise identification of geographic areas associated with a record may be contained in field 052 (Geographic Classification Code) or in field 058 (Other Geographic Classification Code). Subfield $b may be used for a local expansion of a GAC code. GACs are recorded in field 043 in order of importance.

$b - Local GAC code

Local code for a geographic area. The code is formulated by attaching a local subentity code to an already established geographic area code. Each local GAC associated with an item is contained in a separate subfield $b. It is recommended that standard GACs also be included in subfield $a for international exchange and understanding.

See description of this subfield in Appendix A: Control Subfields.

$2 - Source of local code

Code that identifies the source from which the local code was assigned. It is used only when subfield $b is used to indicate a local GAC code.

Codes from: Geographic Area Code and Term Source Codes.

$8 - Field link and sequence number

See description of this subfield in Appendix A: Control Subfields.
